Description

Tests using SSL can block on Jenkins when random entropy is depleted, causing timeouts that trigger test failures.

I found some info about /dev/random problems on FreeBSD here: https://wiki.freebsd.org/201308DevSummit/Security/DevRandom, which lead me to /etc/rc.d/iinitrandom, which gets around the limited entropy by cat'ing a bunch of shit to /dev/random:

( ps -fauxww; sysctl -a; date; df -ib; dmesg; ps -fauxww ) \
      | dd of=/dev/random bs=8k 2>/dev/null
cat /bin/ls | dd of=/dev/random bs=8k 2>/dev/null

I think we should try the same strategy in a crontab every X minutes, to see if that addresses the test failures.
